This happened to one of the shooters on shotgun competition. Firing pin on his Benelli Supernova stuck in forward position and slamfire discharge occured when he pushed forend forward loading shell into a chamber.

The problem was in firing pin. It is little deformed (probably from dry-fire trainings). That caused it to stuck in forward position. It looks like the metal is too soft and easy to deform:

Offtopic today. I own Benelli Supernova shotgun. It was working good for a very long period of time. I’ve put about 15,000-20,000 rounds through it. The only problem I’ve had was a light primer strike on my Benelli Supernova. It was easy to fix.

The key to success to competition shooter is to never stop and try new drills, different stances and of course to experiment with equipment.

Benelli Supernova is a great shotgun but it has some things which can be improved. One of such things is slippery forend. It has groves but plastic is slippery, I wish I could get Hogue overmolded forend for my Benelli Supernova, I miss it so much.

By the way, this is one of things why I love my Rem 870, you can choose from hundreds of upgrades! Accessories for other shotguns are very limited.
